You can also filter output from show commands to display lines containing a specified string, lines
that do not contain a specified string, or output starting with a line containing a specified string.
The search string is a regular expression consisting of a single character or string of characters.
You can use special characters to construct complex regular expressions. Refer to
“Using special
characters in regular expressions” on page 22 for information on special characters used with
regular expressions.
Displaying lines containing a specified string
The following command filters the output of the show interface command for port 3/1 so it displays
only lines containing the word “Internet”. This command can be used to display the IP address of
the interface.
BigIron RX# show interface e 3/1 | include Internet
Internet address is 192.168.1.11/24, MTU 1518 bytes, encapsulation ethernet
Syntax: <show-command> | include <regular-expression>
NOTE
The vertical bar ( | ) is part of the command.
NOTE
The regular expression specified as the search string is case sensitive. In the example above, a
search string of “Internet” would match the line containing the IP address, but a search string of
“internet” would not.
Displaying lines that do not contain a specified string
The following command filters the output of the show who command so it displays only lines that
do not contain the word “closed”. This command can be used to display open connections to a
BigIron RX Series Switch.
Syntax: <show-command> | exclude <regular-expression>
Displaying lines starting with a specified string
The following command filters the output of the show who command so it displays output starting
with the first line that contains the word “SSH”. This command can be used to display information
about SSH connections to the BigIron RX Series Switch.
